pplifttion filed September 23, 1399. Serial No. 781,440. (No modali) To @ZZ whom it wmp concern.:

Be it known that I, JOHN W. MILLER, a citizen of the United States, residing at Akron, in the county oit-Summit and State of Ohio, have invented a new and useful Side Brace for Shafting, ot which the following isa specilcation.

My invention relates 'to improvements in side bra-ces ior shafts employed for drills or in'an-yfether connection, and has for one object the `productionl of a simple, durable, and inexpensive brace for connecting the ends of parallel shafts and designed to oppose resistance 'to side strain.

A further object ofthe invention is to provde simple means for, effecting the longitudinal adjustment or extension of the brace.

Referring to the drawings, Figure 1 is an elevation of a porta-ble machine comprising two shafts with my brace applied.. Fig. 2 is a similar viertP of the brace detached and having a portion broken out in order to aecom-` modate the View on a large scale; and Fig. 3 is an elevation showing the ends of two shafts and my brace applied, the bearing members, being shown in section.

Referring to the numerals of reference on the drawings, designating corresponding parts throughout the several views, 1 indicates a portable machine of ordinary form, comprising the engineshaft 2 and the ilyrrheel shaft 3, upon which are keyed the wheeis Il and 5, geared together', as by a belt 6. These shafts are ordinarily at some distance apart, and being connected by gearing of some form the side strains upon the shafts are considerable. lt is for the purpose of re sisting these strains and of solidly bracing the shafts that ll have provided my novel adjustable brace 7, one duced andslides freely Within a smooth socket 9 in one ot two bearing members 10 and 11, each of which is provided with an opening 12 for the reception ot the reduced ends 13 of the shafts 2 and 3. The end-14 of the brace 7 is also reduced and is screw-threaded to nt Within a screw-threaded socket 15 in the bearing member 11.

end 8 of which is rel ed as indicated in Fig. 1 of the drawings, the

distances between the bearing members may be regulated or adjusted by rotating the threaded ends 14 in the sockets 15 inan obvious manner, the opposite smooth end 8 of the brace revolving in its socket 9, against the bottom of which it finds an abutment.

Any suitable means for locking the brace against rotation toprevent the accidental derangement of its adjustment may be provided; but I prefer to employ one or more set-screws 19, passed through the Wall of the socket 9 and designed to bear against and tix the brace Within the socket.

What I claim is- 1. A side brace for members having (vided with sockets in the end members adapted for alinement, and a rod disposed loosely in one of the sockets at one end and having its opposite end in threaded engagement with the other socket.

2. A side brace for shafts comprising end members having bearings therein, and proided with sockets in the end members, one of said sockets having threads, a rod having a threaded end engaging the threads of one of the sockets and having a smooth end disposed loosely in the'other socket, and setscrews carried by one of the end pieces and adapted for engagement with the rod to hold it against movement with respect thereto.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in the presence of tWo Witnesses.
